Hi! I just signed up to post write this guide, as I couldn't find any info about it anywhere.
What you need is an isofix bracked, two screws and two nuts. I believe there is also a plastic cover for the bracket, but I couldn't find the part number for it.
Here's the backside of the front passenger seat. Start by removing the two small plastic clips on holding the plastic covers on either side of the seat. Do so by pushing the pins in the middle all the way through, then you can pull the clips out.
Remove the adjustment knob on the right side of the seat by simply pulling it out.
Pry out the covers to expose the holes where the isofix bracket is supposed to be fixed.
Fit the nuts to the lower round holes.
Here's one end of the isofix bracket. The round hole is where the screw is supposed to go and the pin goes in the rectangular hole in the seat.
Bracked installed.
Reinstall the pins for the side covers along with the adjustment knob and you're all done. Easy peasy!
